Samsung Galaxy J7 Nxt J701 Firmware (Flash File) Drivers, Tools & Guide
You need the right files to fix a Samsung Galaxy J7 Nxt J701. This guide covers the stock firmware, the correct Odin version, and the steps to restore the device to its original state.
One thing you must do before starting: if your device has a Samsung account signed in, sign it out. If you skip this, the device will trigger a Knox lock. This adds extra work to the process later. Also, Samsung firmware comes in .tar.md5 format. After extracting the ZIP, you should see files named AP_*, BL_*, CP_*, and CSC_* (or HOME_CSC_*). If you do not see these files, you have the wrong package.
The Samsung Galaxy J7 Nxt J701 uses Odin for firmware installation, just like other Samsung devices. The stock firmware ships with Android 7.0 (Nougat) and can be upgraded to Android 9.0 (Pie), One UI. This determines the interface and security features you will see after flashing. The Samsung Galaxy J7 Nxt J701 was released in 2017, which means USB driver compatibility on newer Windows versions (10/11) may require manual installation rather than plug-and-play.
Samsung firmware uses a multi-file system (AP, BL, CP, CSC) that is specific to Odin, unlike single-file scatter-based tools. This page is updated with the latest available firmware builds as they become available.
Your Samsung Galaxy J7 Nxt J701 firmware comes as a compressed ZIP file. Download and extract it using WinRAR or 7-Zip. After extracting, you should see files named like AP_*.tar.md5, BL_*.tar.md5, CP_*.tar.md5, and CSC_*.tar.md5 (or HOME_CSC_*.tar.md5). If you do not see these files, you may have the wrong firmware package for your device.
This process restores the phone to its original factory state, which means all your personal data will be lost. That clean wipe is exactly what fixes persistent problems like bootloops, forgotten locks, Google account verification, battery drain, and system errors.
Samsung Galaxy J7 Nxt J701 FRP Bypass
The fastest way to bypass FRP on Samsung Galaxy J7 Nxt J701 is to use a free Android apps launcher that lets you access settings during the setup wizard. After flashing or performing a factory reset you may see a Google account lock (FRP). Our free Android apps launcher is the fastest way to get past it. This is also why I always recommend removing your Google account before flashing, it avoids this problem entirely.
Samsung Galaxy J7 Nxt J701 Hard Reset Guide
A hard reset clears the data on a Samsung Galaxy J7 Nxt J701 without using a computer. Power off the device completely, then hold Volume Up + Power (for older models with a Home button, use Volume Up + Home + Power) at the same time until the recovery menu appears. Use the volume keys to navigate to “Wipe Data/Factory Reset” and confirm with the Power button.
A hard reset erases all data and restores Samsung Galaxy J7 Nxt J701 to its original factory state. This fixes most software problems, slow performance, app crashes, forgotten screen locks, and bootloops. If the issue persists after a factory reset, a full firmware flash using Odin is covered in the following sections.
Samsung Galaxy J7 Nxt J701 Firmware Compatibility Check
Choosing the wrong Samsung Galaxy J7 Nxt J701 firmware is the most common error. Before downloading anything, verify your exact device identity:
- Identify Your Exact Model Number: Go to Settings › About Phone and note your full model number (e.g. J701). The letter suffix matters, U/U1 = USA, W = Canada, N = Korea, B/F = International/Global. Flashing firmware built for a different variant can cause issues.
- Match the CSC (Region): The 3-letter region code in the firmware filename must match your device. Check Settings › About Phone › Software Information for your current CSC, or look at the Service Provider line in Download Mode. Common codes: XAA (US), BTU (UK), INS (India), SER (Russia).
- Check the Binary Level: Look at the version string in your current firmware (e.g.
XXU9BZDP, the number after the letters is the binary level). You cannot downgrade to a lower binary level. If your device is on Binary 9, only flash Binary 9 or higher firmware. - Confirm the Build Date: The last 4 characters of the PDA version encode the build date, first character is the year (A=2024, B=2025, C=2026), second is the month (A=Jan through L=Dec).
- Verify in Download Mode: Power off, hold Volume Down + Power to enter Download Mode. This screen shows your exact model, CSC, and current firmware version, use this to confirm before flashing.

Which Firmware Version Should I Download?
Use this table to decide which Samsung Galaxy J7 Nxt J701 firmware to download. Find your situation in the table and go straight to the right file:
| Your Situation | What I Recommend |
|---|---|
| Phone is completely dead or stuck on logo | DDS9CTG1, download this one. It is the latest Samsung Galaxy J7 Nxt J701 firmware available. |
| FRP / Google account lock only | See the FRP bypass guide above, you likely do not need the full firmware for this. |
| Not sure which region/CSC to download | Check Settings › About Phone › Software Information for your current CSC, or enter Download Mode (Volume Down + Power), it shows the CSC on screen. Match the 3-letter code (e.g. XAA, BTU, INS) to the firmware filename. |
| Phone slow after a recent OTA update | Try DDU8CSK4, sometimes the latest OTA introduces new bugs and an older build runs better. Make sure the binary level is the same or higher than what your device currently has. |
| IMEI missing after a previous flash | Re-flash DDS9CTG1 first, then follow the IMEI repair guide. Do not skip the reflash. |
| DDS9CTG1 failed with a flash error | Try DDU8CSK4 instead and double-check your AP/BL/CP/CSC file assignments in Odin before assuming the firmware is the problem. |
| Restoring to factory / warranty repair | DDS9CTG1, clean state, fresh start. |
To tell which Samsung firmware is newer, look at the last 4 characters of the PDA version string (e.g. S938BXXU9CZDP). The first character is the year (A=2024, B=2025, C=2026), the second is the month (A=Jan, B=Feb… L=Dec, Z=final stable), and the last two are the revision (0-9 then A-Z, where Z is highest). But before comparing dates, always check the binary level: the digit just before the date code (e.g. XXU9CZDP = Binary 9). You cannot downgrade to a lower binary level. If your device is on Binary 9, only flash Binary 9 or higher. Also make sure the 3-letter CSC code in the firmware matches your device region.

Important: The Samsung Galaxy J7 Nxt J701 (J701) should not be confused with other Galaxy J7 Nxt variants that may have different chipsets or regional firmware. Even devices in the same Galaxy J7 Nxt line can use completely different processors. Always verify your exact model code “J701” in Settings > About Phone before downloading any firmware from this page.
- The model code on your phone must match J701 exactly. Even a single letter variant (like adding or dropping an “i” or “s”) can mean a different chipset inside.
- Your chipset should be Samsung Exynos 7 Octa 7870 (Mali-T830 MP1 GPU). Recovery mode shows this information if you are not sure.
- Do not mix firmware from other download sites with the files on this page.
- If the downloaded file is much smaller than what is listed in the table above, re-download it, partial files will fail.
Prerequisites for Samsung Galaxy J7 Nxt J701 Firmware
Go through this list before you open Odin for the Samsung Galaxy J7 Nxt J701. Two things that commonly cause problems with Samsung devices: a Samsung account that was not signed out before flashing, which can trigger KG lock, and a USB cable that works for charging but drops the connection mid-flash. Always use a proper data cable, not a charge-only cable.
- Write Down Your IMEI: Open your phone dialer and type *#06#. Take a photo of the screen showing both IMEI numbers. You may need these later to fix your IMEI if it gets wiped during the flash.
- Sign Out of Google: Open Settings, go to Accounts, and remove every Google account from the device. If you skip this, Google will lock the phone after flashing and you will need to do an FRP bypass.
- Remove Samsung Accounts: Sign out of all Samsung accounts to avoid KG lock.
- Save Your Files: Copy everything important to a PC or cloud storage. After flashing, the phone will be completely empty, no apps, no photos, no messages.
- Battery Check: Charge to at least 50%. If the phone dies during flashing, you could end up with a device that will not turn on at all.
- Get the Right Cable: You need a USB data cable, the kind that can transfer files, not just charge. Plug it into a USB 2.0 port on a Windows PC for the most reliable connection.
- Set Up Drivers:
Samsung Galaxy J7 Nxt J701 Firmware Installation Guide
Follow these steps to install the Samsung Galaxy J7 Nxt J701 firmware using Odin. A quick tip: keep “Auto Reboot” and “F. Reset Time” both checked in Odin, those two options together give you the cleanest flash result. If you are not sure which Odin version to use, check our Odin versions page. Some older Samsung devices work better with older Odin builds.
- Prepare the Flash Files:
- Go to the download section and grab the firmware package that matches your device.
- Unzip the file to a folder on your desktop. Avoid using folder names with non-English characters or spaces, the flash tool may not read them correctly.
- Confirm Driver Setup:
- The drivers listed in prerequisites need to be installed and working before you connect the phone. If you are not sure, reinstall them and restart your computer.
- Load the Firmware File:
- In Odin, click “BL” and select the BL_*.tar.md5 file. Click “AP” and select the AP_*.tar.md5 file. Repeat for “CP” and “CSC”. Use HOME_CSC to keep data, or CSC for a clean flash.
- Connect Your Device:
- Enter Download Mode: Turn off your phone, then hold Volume Down + Power (add Home button on older models) until the warning screen appears. Press Volume Up to confirm and enter Download Mode.
- Connect your phone to your PC via USB. Odin should show “Added..” in the log area, this means your device is detected.
- Start Flashing:
- Click “Start” to kick off the firmware write.
- Hands off the phone and cable until the tool shows completion. Moving or disconnecting the device mid-flash is the most common cause of a bricked phone.
- Wait and Reboot:
- When you see the success message, disconnect the USB cable.
- Hold the power button to boot the phone. Give it a solid 5 to 8 minutes for the first startup, this is normal.

Common Issues When Flashing Samsung Galaxy J7 Nxt J701
- Odin Shows “FAIL” Instead of “PASS”:
- This is usually a mismatch between the firmware region or model and your device. Confirm your exact model number in Settings › About Phone before selecting the firmware. Even a single letter difference in the model code matters.
- Samsung Galaxy J7 Nxt J701 Not Recognized by Odin:
- Reinstall the Samsung USB drivers. Make sure you are in Download Mode. Try a different USB cable, Odin can be sensitive to cable quality.
- KG Lock / Knox Triggered After Flashing:
- This happens when a Samsung account was still signed in before flashing, or when unofficial firmware was used. Always sign out of Samsung accounts before flashing. If KG lock is already active, a professional unlocking tool is generally needed.
- Boot Loop After Flashing:
- Enter recovery mode (Volume Up + Power) and perform a factory reset. This clears any leftover data from the previous firmware that may be causing the conflict.
Post-Flash Behavior on Samsung Galaxy J7 Nxt J701
Here is what is completely normal after a successful flash:
- How to know the flash was successful: Odin will show “PASS.” in green text at the top-left of the log area. If you see this, everything went fine.
- Wi-Fi, Bluetooth, and mobile data should all work right after setup. If mobile data is not connecting, go to Settings, SIM and Network, and re-enter your APN manually, the flash sometimes clears carrier APN settings.
- The phone may ask for language and region again, this is normal after a flash. You are starting from a clean state, so the setup wizard runs just like when the phone was brand new.
- The phone will feel warm during first boot, this is normal. It settles after a few minutes once the initial app setup is complete.
- Stuck in a bootloop after first boot? Enter recovery mode and do a factory reset from there, see the hard reset guide above. This can happen occasionally and does not mean the firmware is wrong.
- Be careful when re-adding your Google account, if you did not remove it before flashing, you may see an FRP prompt. Add it fresh during the setup wizard, not afterwards through Settings.
- Battery percentage may seem inaccurate for the first day. The battery statistics are calibrated during normal use. Charge the phone fully once without interruption and the readings will stabilize.
Missing IMEI or Corrupt Baseband on Samsung Galaxy J7 Nxt J701 After Flashing?
A missing IMEI on a Samsung device after flashing usually points to a corrupted EFS partition, this is the partition that stores your IMEI and carrier settings. Note that restoring an IMEI that is not your original number is illegal in most countries, so only do this if you are restoring the number the device had before you flashed. Tools like ChimeraTool or BFT can help with this. Check your local laws before proceeding.

Samsung Galaxy J7 Nxt J701 Firmware FAQ
Q1: Is it safe to flash during a power outage risk?
A: It is best to avoid flashing during unstable power conditions. If your PC shuts down during the flash, it can corrupt the write and leave the phone in an unbootable state. If you are in an area with unreliable power, use a laptop with a fully charged battery instead of a desktop.
Q2: What should I do if I encounter an FRP lock after flashing?
A: Use our free Android apps launcher. FRP lock activates when a Google account was still signed in before flashing. This is why signing out of your Google account before flashing avoids this issue entirely.
Q3: Will flashing void my warranty?
A: Flashing official stock firmware generally does not void your warranty since you are restoring the device to its factory-intended state. However, some manufacturers may flag that the bootloader was unlocked or that the flash counter increased. Check your specific warranty terms with Samsung support if you are concerned.
Q4: Will flashing erase my data?
A: Yes, flashing with Odin restores the device to factory state, including Android 7.0 (Nougat), upgradable to Android 9.0 (Pie), One UI default settings. All apps, photos, contacts, and accounts will be removed. Back up everything you need before you start. There is no way to recover data once the flash is complete.
Q5: My IMEI shows “unknown” after flashing. Is my phone permanently damaged?
A: No, it looks alarming, but it is fixable. Follow the IMEI repair guide in the troubleshooting section above. For Samsung devices, check for EFS partition corruption first. Do not insert a SIM card until the IMEI is restored.
Q6: How long does the flashing process take?
A: The actual flash usually takes between 3 and 10 minutes depending on the firmware size and USB connection speed. The first boot after flashing takes another 3 to 8 minutes. Do not interrupt the device during either stage. If the progress bar in Odin appears stuck, give it a few more minutes before assuming something went wrong.
Q7: Can I flash this firmware if my phone does not turn on at all?
A: Yes, in most cases. Samsung devices can usually enter Download Mode even when the screen is completely dead, hold Volume Down + Power for 10 seconds. If the battery is completely drained, charge it for at least 15 minutes first.
Q8: Is this firmware compatible with other Samsung models?
A: No. This firmware is built specifically for the Samsung Galaxy J7 Nxt J701 running on the Samsung Exynos 7 Octa 7870 (Mali-T830 MP1 GPU) chipset. Even variants of the Galaxy J7 Nxt with a different letter suffix can have a completely different chipset inside. Flashing the wrong firmware can leave your phone in a state that is very difficult to recover from. Always check your exact model number in Settings.
